Abstract:The paper addresses the effect of a compost prepared from tobacco wastes with an admixture of bark and straw on the enzymatic activity and certain chemical properties of a grey-brown podzolic soil amended with that compost.The study was conducted under the conditions of a pot experiment in which the soil material was collected from the surface horizon of the grey-brown podzolic soil. The effect of the application of the compost was compared with soil without such amendment. The test plant was maize cv. Kosmo 230. Fertilisation of the light soil with the compost studied caused changes in the enzymatic activity of the soil that were related both to the dose of the compost and to the kind of enzyme studied. With increase in the dose of the compost there was an increase in dehydrogenase activity (highest dose) and a signifi cant decrease in the activity of acid phosphatase. Moreover, it was observed that tobacco compost was a signifi cant source that enriched the light soil in organic matter, total nitrogen, and available forms of phosphorus, magnesium and potassium, which was evident in increased yields of maize grown as the test plant.Signifi cant correlations were also demonstrated between a majority of the biochemical and chemical parameters, which indicates that those parameters characterise well the biological properties of a grey-brown podzolic soil amended with tobacco compost.

“…Its activity can provide useful information on organic P mineralization potential and biological activity of soils (Speir and Ross, 1978;Dick and Tabatabai, 1993;Krämer and Green, 2000). Acid phosphatase activity has been used as an indicator in several studies to evaluate P limitation in forest ecosystems (Schneider et al, 2001;Gress et al, 2007).…”

Effects of precipitation on soil acid phosphatase activity in three successional forests in southern China

et al. 2011

Abstract. Phosphorus (P) is often a limiting nutrient for plant growth in tropical and subtropical forests. Global climate change has led to alterations in precipitation in the recent years, which inevitably influences P cycling. Soil acid phosphatase plays a vital role in controlling P mineralization, and its activity reflects the capacity of organic P mineralization potential in soils. In order to study the effects of precipitation on soil acid phosphatase activity, an experiment with precipitation treatments (no precipitation, natural precipitation and doubled precipitation) in three successional forests in southern China was carried out. The three forests include Masson pine forest (MPF), coniferous and broadleaved mixed forest (MF) and monsoon evergreen broadleaved forest (MEBF). Results showed that driven by seasonality of precipitation, changes in soil acid phosphatase activities coincided with the seasonal climate pattern, with significantly higher values in the wet season than in the dry season. Soil acid phosphatase activities were closely linked to forest successional stages, with enhanced values in the later stages of forest succession. In the dry season, soil acid phosphatase activities in the three forests showed a rising trend with increasing precipitation treatments. In the wet season, soil acid phosphatase activity was depressed by no precipitation treatment in the three forests. However, doubled precipitation treatment exerted a significantly negative effect on it only in MEBF. These results indicate that the potential transformation rate of organic P might be more dependent on water in the dry season than in the wet season. A decrease in organic P turnover would occur in the three forests if there was a drought in a whole year in the future. More rainfall in the wet season would also be adverse to organic P turnover in MEBF due to its high soil moisture.

“…According to Schneider et al (2001), the high concentration of acid phosphatase in the substrate means that there is a deficit of available phosphorus. Phosphatases are capable of hydrolysing phosphorus organic compounds in the amounts exceeding plants' demand for this element (Tarafdar and Rao, 1990).…”

Summary. The objective of the study was to determine the dynamics of the enzymatic activity in a substrate containing a microbiological inoculum (Effective Microorganisms -EM) intended to improve French marigold growth and flowering. The material used in the study was peat substrate of 5.5-6.0 pH into which plants were planted and then inoculated with different doses of the EM biofertilizer (1 : 10, 1 : 50, 1 : 100). Samples of the substrate on which experimental plants were cultivated were collected during the following three phases: the phase of seedling planting, the phase of vegetative growth and the phase of flowering. The scope of investigations comprised determination of the activity of dehydrogenases, urease and acid phosphatase activity by the spectrophotometric method. In addition, the following plant morphological analyses were performed: plant height, shoot number and length, number of buds and inflorescences, and leaf greenness index (SPAD). It was found that the phase of plant development was proved to be the main determinant of the activity of the enzymes under study. The EM biofertilizer had positive * The study was supported by NCN (National Science Centre) grant no.

The EM biofertilizer concentrated at 1 : 100 and applied into the soil and foliage resulted in a larger number of darker leaves and greater number of inflorescences on the plants.
